Parts are not returnable even if not as advertised
I ordered an OM chair with arm rests that are supposed to come to 9" above the chair cushion for an extra $75. I am 5'4" and the the armrests are not tall enough to reach the bottom of my forearms when parallel to the seat, coming only 8" from the top of the seat. When I asked the company if I could return the arm rests, they said no and that the measurement is only approximate. There is no customer satisfaction guarantee so I would recommend purchasing at a store so you can try the product and not ordering through the website.
